Patented Dec. 29, 1914:.

Application filed January 8, 1914. Serial No. 811,085.

To all whom it may concern:

Be it known that I, GEORGE H. BRYANT, a citizen of the United States, residing at Windsor, in the county of Bertie and State of North Carolina, have invented certain new and useful Improvements in Sash- Holders; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in sash holders.

The object is to provide an improved form of friction shoe for holding a screen or sash in raised or lowered position.

With the above objects in view, the invention resides in certain novel features of construction and combination herein described and claimed and shown in the drawings wherein Figure l is an inner side view of a portion of a window frame showing the application of my improved shoe to a window screen, parts thereof being broken away and in section; Fig. 2 is a horizontal sectional view on the line 22 of Fig. 1; Fig. 3 is a vertical section on the line 3-3 of Fig. 2; Fig. 4 is an outer edge view of one of the friction shoes; Fig. 5 is a similar view with the screw and yoke, hereinafter described, removed; and Fig. 6 is a detail horizontal section on the line 66 of Fig. 1.

In the embodiment illustrated in the accompanying drawings, I have shown a window frame F carrying the usual guide strips S, located on the opposite sides of the frame and in close proximity to the lower sash L. Slidably mounted between the guide strips S is a screen frame 1, the opposite edges of which are channeled as at 2 for the reception of said strips S.

Located within the groove 2 on one side of the screen frame, are upper and lower pressure exerting springs 3, here shown in the form of flat leaf springs having one end secured within the groove 2, their central portions being bulged outwardly and their opposite ends contacting with the inner wall of the groove.

Disposed within the grove 2 at the opposite side of the screen frame, are friction shoes 4.- which constitute this invention, each of said shoes being formed by bending a flat piece of metal to form a back plate 5 and lateral side flanges 6. The back plate 5 is provided with a central opening 7 and with transverse slots 8 spaced between said opening and the opposite ends of said plate. Fastening screws 9 are threaded into sleeves 10, fastened in any suitable manner within the strips on this edge of the screen (or if 1' so desire, I may use wood screws without the sleeves), and said screws, as clearly shown in the drawings, are in alinement with the openings 7 in the back plates 5, and have their heads contacting with the inner sides of said back plates.

Flat metal strips 11 have their central portions bulged slightly outward as at 12 and provided with central openings 18, the free ends of said strips extending inwardly through the slots 8, lying between the flanges 6 and having their terminals bent around the opposite ends of the back plates 5, the heads of the screws 9 being swiveled between the outwardly bulged portions 12 of the strips 11 and the back plates 5. The portions 14 of the strips 11, lying between the flanges 6, are bowed slightly outward, thus forming resilient friction faces for engagement with one of the strips S.

By the above described construction, it will be clearly seen that the fastening screws are at all times maintained in proper position upon the friction shoes, thus obviating any necessity of furnishing independent fastening elements with the shoes, it being understood that said shoes may be manufactured and sold separately from the screens, as well as in connection therewith. WVhen sold separately, however, wood screws are preferably furnished, said screws being adapted to be sunk into the edges of the screen frames.

By reference to Fig. 3 it will be seen that the friction shoes are disposed in such position as to cause all of their lateral thrust to be exerted upon the upper and lower cross bars of the screen frame, thus preventing the side bars of said frame from becoming bowed inwardly and causing the wire to buckle.

The screen frame 1 is of less width than the inside of the frame F and the grooves 2 are of such depth as to allow the entire screen frame to be pushed to one side against the tension of the springs 3, this operation bringing the other edge of the screen inwardly a distance sufficient to allow it to be disengaged from the strip S and thus allow the entire screen to be removed from the window.

On account of the screen frame being of less width than the inside of the window frame, I provide curved leaf springs 15 at the tops of the edge strips of the screen frame, said leaf springs being adapted to contact with the inner sides of the window frame and thus prevent flies or mosquitos from entering at these points.

Having thus described my invention, What I claim is l. A device of the character described comprising a longitudinally channeled shoe having an opening through its back and transverse slots spaced from said opening, a yoke spaced from the back of said shoe and having its ends passed through said slots and seated within the channel of said shoe, said yoke having an opening alined with the opening in said'shoe, and a screw passing through the opening in said yoke and having its head disposed between the back of said shoe and said yoke.

2. A device of the character described comprising a channel shaped member having a back plate and side flanges, said back plate having a substantially central opening and transverse slots between said opening and the ends of said member, a strip of metal spaced from said back plate between said slots and having its end portions extending through said slots, disposed between said flanges and bent around the opposite ends of said back plate, the central portion of said strip having an opening alined with the opening in said back plate and a screw having its shank projecting through the opening in said strip and its head disposed between the central portions of said strip and said plate.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

GEORGE H. BRYANT.
